vaccin--Sorry, I mean.-- Updates are not always the best solution. Up to windows 8.1 I used to disable windows update and run them manually once or twice a year when I felt I could invest the time. I hate win10 and above and I'm not counting on them. I have a notebook with win10. I could not...

Car spark plugs run at ~12.000 V !! it hurts but a spark won't kill you. Wall outlet is 110V (usa?) but in CAN kill you. This is a crude simplification but it might work: Let's think energy as water. Your needs are expressed in gallons per minute, Amount of water that flows over a time span...

wow that was lightning fast. Thanks a lot ! I'll try to get an adapter and see what happens. Regards

Hello!, I have two Pylontechs UP2500 ("24V" 100Ah) and I am currently calculating the SOC with an external shunt and a raspberry pi. My SOC solution is inaccurate so it syncs to 100% whenever the system is full. Yet if a whole week passes by and the battery oscillated (ie between 20% and 75%)...

I only have 6 panels. Perhaps I could arrange 3 horizontals and 3 tilted. That way I could put the horizontal string "first" and no panels would get shaded by other panels. Not easy though

Thanks for the replies ! I tried the PVWatts thingy. I used the actual position with an approximated array size. Then run the same test changing the tilt. Here are the results. The annual production is not important as the calculator is probably assuming I would stick with the angle the whole...

I'm having discussions in my head regarding how many watts would I gain if I put my panels in the correct angle. I have 6 panels on a 10th floor roof that has lots of wind. I went with the simplest and safest approach and made an horizontal structure. Panels are 100% horizontal. They produce...

Oh... So now, pecific gravity it's not enough, now you need to pay attention to 'center of gravity' to prevent scams! ...Later on... scammers will use precision instruments to replace the concrete with similar density materials. future is dark! :ROFLMAO:

I don't want to be a d*ck, but the man in the video is using some sort of Pot mixture. I have reasons to believe he might not be a true gardener

I don't have an answer, but the racks that can hold full length servers we can speculate a bit. A 2U server full of mechanical disks, two power supplies and such may climb above 25 Kg each. 48U racks usually are sturdy beasts. The smaller racks might be tricky for they might be commercialized...

Yeah, about that Rack.... those packs were really expensive. The Rack will have to wait :ROFLMAO:

I found (totally stole) this one:

You are not mentioning what your load is. Could it be a low voltage disconnect from the inverter ? Big loads could be pulling battery voltage lower than the inverter's threshold maybe?

Hello there, If I recall correctly you should have no problems. Each MPPT should have it's own panel(s). Regarding DIY LFPs and BMS I don't have the knowledge. Noting that my limitied experience is with a stationary project, consider the following: a. Regarding chargers... I recently went the...

I'm not a power user so don't take my words too seriously. If you took the time to check mosfets, you could check if the relays work (be careful with polarity if you don't desolder them to test). Also, if I'm not crazy, I recall most of these units claim that they feature with a reverse polarity...

Ok. Got it. Currently shopping for a soft hammer :ROFLMAO: Thanks

I finally got an LFP battery ( pylontech 100Ah ). I was using a lead acid bank (LOTS of small SLAs and a pair of GEL) heavily degraded ( around 480 Ah total from which I was able to pull 90~110 Ah ). I would like to purchase more pylontechs but I don't think that will be possible for a year or...

the most impressive technology behind the product would be the CD player anti-shock. That gun better have a good recoil absorption mechanism. The powerhouse is no doubt seebeck-effect based. Gotta keep shooting to power the other devices.

I finally did it. Bought a pylontech UP2500. Seems working fine. But I have some questions. SHORT story: Battery seems to work OK. There are lot of different approaches to BULK and floating voltage limits and I'm afraid to set them to somthing that might reduce the lifespan. First day I set...

I have one of the usb microscopes and despite the fact that are cheap and incomparable with the real things... I never had a "real thing" at reach. I grew up with paper manuals at school that had a few printed images of what you would see with a microscope. I am happy this 30 bucks microscope...

Personally, I'm a fan of Emerson's GXT series. I Also recommend them! I bought a used GXT2 2kva unit a few years back. The only thing I didn't like about it is that my model was not able to cold start. Is the GXT3 able to cold start? offtopic: My first glances at solar power was running this...

Sorry! This is the one that works fine: EDIT!: I got the pictures off internet but the one I have says 6A instead of 10A** I'm sure my monitoring solution won't tell the real story in regards to the startup peak, but the overall consumption of the fridge is quite low. I've installed the...

after messing around for quite a while I ended up replacing the relay and the new one, different brand, seems to work fine

** before I forget: my grid runs at 220VAC, single phase. ** I have bought an 8 pin relay. The purpose is this: I want a small fridge to run on solar by day and use the grid by night. This would save power during the day and preserve my already-very-small lead acid bank when no power is being...

expensive and custom built LiFePO4 batteries are SLOWLY becoming available here in Argentina. Before I get too carried on putting my sky mask grabbing the rolling pin and heading to the bank asking for donations... I have a cheap MPP solar clone inverter that is not compatible with lithium...

If I insult you and delete it, did I insult you? If I threaten to harm you and I delete the threat, did I threaten you? Where is the world going with all these "self destructing messages"; the possibility to recall sent (and read!) messages. The messaging platforms suddenly lost reliability...

I think it would be hard to balance, and-or the need for more mobile parts that require maintenance inside a vacuum chamber makes it more expensive? There are very little attempts at DIY. If you search for diy flywheel battery 75% of results at youtube will say "free energy". Even if you...

I just saw the video and I wanted to say what I think. Will, you're a surgeon. You have the ability to dissect a subject with presicion to mitigate political debate without censuring yourself. 1: What I LOVE about this forum is that everyone can speak out. Rules must be respected, of course...

Hello there, I'm trying to make a simple kettle heater of sorts. That is, a somewhat heavy, flat base with the coil, that get's hot so you rest a kettle on top. I'm bad at describing things and I don't speak english as I would like. I never used kanthal before and I'm not exactly sure how to...

Based on absolute ignorance I set 1 year and 1 gigabyte (whatever comes first) as a limit. I just did this so I'll tell you as time passes ? I'm very used to PRTG historic reports so much that I was about to export the .prom file via SNMP to my home PRTG server. But If the grafana approach can...

I'll reply to myself in case any other newbie with systemd like me is struggling with this: The parameter '--storage.tsdb.retention.time=xxx' is part of the ExecStart= line. This line is truncated by a backslash at the end of every line (except the last one). If you were to add the storage lines...

After several months I'm quite pleased with the monitoring solution. I wanted to ask how to expand the data retention. I was surprised that prometheus only retains 15 days of data. I found a parameter that could be configured in the service file '--storage.tsdb.retention.time' Yet, it won't...

Thanks everyone for your answers! I'm on an extremely tight budget, so you will notice that my system is not standard, as safe as it should be, or properly sized. I know I'm taking some risks with this. My plan is to upgrade to proper wiring and connectors as time passes and I'm able to afford...
